Really? What will they use to build the legs to support it?

Those aren't legs, they're guy wires.

I said the physics works. The engineering is a totally different question.

"I said the physics works. The engineering is a totally different question."

So if the engineering is questionable or unrealistic, how is it less fanciful?
